Study Notes
Meat-Borne Diseases
- Meat-borne diseases are a significant concern in the Asia-Pacific region.
- Salmonella typhi (typhoid) accounts for a substantial portion of disability-adjusted life years (DALYs).
- 50% of the disease burden in Southeast Asia stems from bacterial diarrheal agents.
- Leading bacterial diarrheal agents (in decreasing order of significance) include enteropathogenic Escherichia coli, non-typhoid Salmonella, and enterotoxigenic E. coli, and Campylobacter spp.
- Foodborne parasites, such as Paragonimus spp., Clonorchis sinensis, and Opisthorchis, pose a significant threat, primarily in the South East Asia B region.
- In the Western Pacific region, helminths account for 55% of disability-adjusted life years (DALYs), with Paragonimus spp., Clonorchis sinensis and Taenia solium as the primary pathogens.
- Bacterial diarrheal diseases account for a smaller percentage (14%) of the foodborne disease burden in the Pacific region, with Campylobacter being the most prevalent pathogen.
- Poultry meat is frequently implicated in gastrointestinal infections.
- Infections in poultry may be associated with contamination during hatching, growing periods, and various stages of handling including transport, scalding, plucking, and evisceration.
- Key pathogens associated with poultry meat include Salmonella spp., Campylobacter spp., Aeromonas spp., Yersinia, Escherichia coli, Mycobacterium avium, as well as Clostridium perfringens, and C. botulinum, and Staphylococcus aureus and Listeria monocytogenes.
Key Diseases from Poultry
- Poultry meat is a frequent source of human gastrointestinal infections.
- Contamination occurs during various stages, potentially causing asymptomatic carriage in birds.
- Farm conditions, transportation procedures, and processing methods significantly impact contamination.
Salmonella spp.
- Salmonella is a prevalent pathogen in poultry, accounting for a significant percentage of foodborne outbreaks.
- Various Salmonella serotypes are frequently found in poultry, associated with gastroenteritis among humans. (88.1%)
Campylobacter spp.
- Campylobacter spp. are increasingly implicated in human enteritis linked to poultry consumption.
- The bacteria reside in the intestines of birds, and their presence in poultry meat and by-products can contribute to outbreaks when hygienic measures are inadequate.
Contamination in Production
- Microbial load is a key concern affecting poultry products.
- Contamination can occur throughout the production cycle, necessitating comprehensive hygiene practices throughout evisceration.
Proper Meat Handling Practices
- Contamination can occur during transportation, processing, and storage.
- Maintaining strict hygiene practices, like separating batches, cleaning and disinfection, and proper temperature control, are essential for reducing the risk of contamination.
- Keeping poultry properly chilled or frozen can help control microbial growth.
- Strict hygiene in the processing and handling is critical to prevent contamination
Poultry Meat Contamination Prevention
- Implementing stringent measures across the food chain from farm to consumer is critical. (Transportation, slaughtering, handling etc.)
Pork Diseases
- Pork products are another significant source of foodborne diseases.
- Proper HACCP guidelines must be strictly applied.
- Contamination with pathogens like Salmonella spp., Campylobacter spp., Yersinia enterocolitica, and Listeria monocytogenes is possible.
- Teania solium and Trichinella may be problematic, often linked to foodborne illnesses.
Microbiological Hazards in Pork
- Contamination of pork/pork products by pathogenic bacteria is often associated with human illnesses.
- Control mechanisms in the food chain, from farm to consumer, are essential for mitigating these risks.
Foodborne Disease Outbreaks
- Data indicate that pork and poultry are leading causes of foodborne illness outbreaks.
- Hygiene practices along the supply chain are vital to minimize these events.
- Proper, systematic control/management systems from farm to fork limit risks significantly.
Data on Foodborne Diseases
- Data on specific pathogens, outbreak numbers, and geographical locations can help shape targeted prevention strategies .
